The best costume that one of our kids ever did was...a Halloween table!!!
You get a piece of cardboard the size of a card table or smaller and "set" it with a paper Halloween tablecloth and plates and cups, which you glue at the 4 place settings. Then you cut a hole in the center and poke your head through. Someone decorates your face like a jack-o-lantern centerpiece, complete with orange face and green hair pulled on top of your head.
Our daughter won $50 for her costume in a huge contest!
